DIN 1. is specially used for Plastic injection die moulds. The characteristics of a material are right sharpening, photo-etching properties with high purity and good homogeneity. DIN is upgraded version of plastic mold steel 0f , which normally supply in Pre hardened condition. Hardness in as supplied condition 280-320 HB with having uniform hardness. The additional nickel content of 1 % increases through hardening. It has good machinability, suitable for Texturing, fine polishability, adequate corrosion resistance, vacuum-degassed steel.

DIN is a premium mold steel that offers excellent polishability, wear resistance, and toughness, making it ideal for a wide range of tooling applications. DIN is a specially designed mold steel with improved toughness and excellent machinability compared to standard P20 grades.

DIN 1. is a widely used cold work steel, especially in the plastic mold industry. It is equivalent to P20+Ni and AISI P20+Ni tool steel. DIN steels have superior polishability compared to 1. (AISI P20+S) and better machinability. To enhance the hardness and wearability of the mould surface material , it can be treated with nitrogenation and flame hardening. DIN steel is melted in an electrical furnace and refined using a VOD or DH equipment.

Chemical Composition:
DIN : Carbon (C): 0.35-0.45%, Manganese (Mn): 1.30-1.60%, Silicon (Si): 0.20-0.40%, Phosphorus (P): &#; 0.030%, Sulfur (S): &#; 0.030%, Chromium (Cr): 1.80-2.10%, Nickel (Ni): 0.90-1.20%, Molybdenum (Mo): 0.15-0.25%

P20+Ni: Carbon (C): 0.28-0.40%, Manganese (Mn): 0.60-1.00%, Silicon (Si): 0.20-0.80%, Phosphorus (P): &#; 0.030%, Sulfur (S): &#; 0.030%, Chromium (Cr): 1.40-2.00%, Nickel (Ni): 0.80-1.20%

Mechanical Properties:
DIN :
Tensile Strength: 980- MPa
Yield Strength: &#; 800 MPa
Elongation: &#; 15%
Hardness: 280-325 HB

P20+Ni:
Tensile Strength: - MPa
Yield Strength: &#; 900 MPa
Elongation: &#; 12%
Hardness: 280-325 HB

Physical Properties:

Density: DIN and P20+Ni have a density of approximately 7.85 g/cm³.
Thermal Conductivity: The thermal conductivity of these steels is around 30-35 W/(m·K).
Specific Heat Capacity: The specific heat capacity is about 460-480 J/(kg·K).
Thermal Expansion: The linear coefficient of thermal expansion is approximately 11-12 x 10^-6 /K.

Application:
DIN is applicable for large & small plastic mould dies for Automotive Industries, Dies for Domestic goods , High finishing plastic Die, Boaster Plates of Presses, Die Holders & Shoe blocks for drop Hammers, Press Cassettes , Upsetter Blocker, forging dies, Different dies & mold for plastic products etc.

DIN 1. steel is one kind of plastic mold steel, equivalent to AISI P20 +Ni tool steel. While Nickel, chromium and molybdenium are the alloying elements for hardness and toughness. 1. tool steel is specially designed for plastic mold industry, especially for big steel mold parts.

Surface Finish: Black Surface, Roughly Machined, Peeled & Turned or as per given requirements.

6. Heat Treatment of Mold Steel 1.

• Heat Treatment of

Usually already pre-toughened, no heat treatment required, if there is no special requirements.

• Soft annealing,

710 to 740 °C for about 2 to 5 hours; then cool slowly of 10 to 20 °C per hour to about 600 °C further cooling in air, This will produce a maximum Brinell hardness of 235.

• Hardening:

Harden from a temperature of 840-870°C followed by oil, then quenching in oil/hot bath/air 180~220 °C. Hardness after quenching is around 52 HRC.

• Tempering of material

Slow heating to tempering temperature immediately after hardening; and minimum time in furnace: 1 hour per 20 mm part thickness; tempering twice is recommended.
